# ADR 0035: Restore Keeps The Original Name; Conflict Is A Clear Error

## Status

Accepted. **Supersedes ADR-0033** (restore de-duplicates the node name on sibling
conflict).

## Context

ADR-0033 made restore auto-rename to `原名(已恢复)` on sibling name conflict so
restore never fails. In practice the suffix is unwanted noise - operators expect the
original name back and prefer to resolve conflicts themselves.

## Decision

Restore clears `deletedAt` and keeps the node's **original name**. If an active
sibling now occupies the same name (D14 partial unique index), the service throws a
`409 name_conflict_on_restore` with a human-readable message ("同名节点已存在，请先
重命名现有节点再恢复") - no silent renaming, no suffix. The restore audit records
the original name only.
